What if Support Role was Added to FFXIV?

[Shibi]

Would it make sense to add a fourth role to the Trinity of Tank, Healer and DPS to help create a better balance between all the job classes?

I'd love it, I just fear it's 15 years too late for this game as it really needs to be locked in from the start, not all stripped away as they have class after class after class.

It's no good having cc/support if there is nothing to cc/support and when the game is build on a Leeeeeeroy Jenkins zerg wall to wall - doesn't matter if its a squishy wall to wall pull either.

Pure Trinity really doesn't exist in this game.
